I'm interested in importing staffing building materials to Douala port, Cameroon. I also want to be in direct connection with the manufacturing company and obtain the price list, etc. We intend to import 4 containers of the staffing molding powder each month and can increase. Please provide your price and the cost of transport to Douala port of Cameroon, Central Africa.
